Application pressure: 1.6MPa, 2.5MPa, 4.0MPa, 6.4MPa, 10MPa

Liquid ammonia shut-off valve refers to a valve whose closing element (valve disc) moves along the centerline of the valve seat. According to the movement of the valve disc, the change in the valve seat opening is directly proportional to the stroke of the valve disc. Due to the relatively short opening or closing stroke of the valve stem and its highly reliable shut-off function, as well as the proportional relationship between the change in the valve seat opening and the stroke of the valve disc, this type of valve is very suitable for regulating flow. Therefore, this type of valve is very suitable for cutting off, regulating, and throttling purposes.

Advantages:

① Simple structure, small size, light weight, and low consumables, not suitable for large caliber valves;

② Quick opening and closing, low flow resistance;

③ Can be used for media with suspended solid particles, and can also be used for powder and granular media depending on the strength of the sealing surface. Suitable for bidirectional opening, closing, and adjustment of ventilation and dust removal pipelines, widely used in gas pipelines and waterways in metallurgy, light industry, power, and petrochemical systems.
